That's some good news, did the WDTV also show the menu?

No; it only plays the film. This is also the case with DVD and AVCHD ISOs. The lack of menus doesn't bother me though.

Back on topic, I can only find a BD-50 of ROTJ in the usual place: it's the one with the audio fix. Was there no BD-25?

I've been trying to download it, but the download has stopped half the way through, and the files I have downloaded all seem to be incomplete. I don't know if I will be able to recover this archive, even with PAR files. :-(
